Polymerase Chain Reaction (PCR) is a technique to amplify the amount of DNA fragments.

The whole process of PCR
What the PCR method is doing is basically just raising and lowering the temperature. That is why this process is called thermal cycling.
Thermal cycling consists of 3 steps.
The first step, denaturation (90℃), will decompose double-stranded DNA into single-stranded DNA
